Please Help... In Drastic Need of Smart Folk

An attention blink is a short time in which information is not registered in the brain.

Our project is to determine if participants are more or less likely to recall the words if they are in color. We will have two groups. They will have the same words/characters, basically be the exact same except one set will have the letters/or symbols in alternating colors(red,orange,blue, purple,green,pink, but not in that order, any order, any color but yellow) and the other in just black in white. We want the slides(each word or symbol) to begin to transition after 200milliseconds for the first 10 slides then for the next 10 to raise the transition time to 300 milliseconds then after another 10 slides to transition at 400 and for the last 6 slides to transition at 500 seconds.

We want the backround to be white on them all and for the font to be times new roman probably a font size around 18. We do want it to be full screen. I think a countdown from five would be good. The program can just close after the 12seconds the program runs. Just remember we need two sets or if there was a way to have a screen at the begining in which we could choose the "color trial" and another option that said "black and white trial" and we could click on either one to choose which application we wanted to start
